Shared place 1 of 25 options for cybersecurity (professional tools and general assistants) on GDPR profile. 5 options, like ChatGPT, have a strong profile. Each tile is an option we track for this field; click through for the check.
Published safeguards
EU data residency available for Enterprise, Edu and the API. Business and API data are not used for training by default; consumer tiers (Free/Plus/Pro) are, unless you turn this off.
How to use ChatGPT safely
- Use the business variant and sign a data processing agreement (DPA).
- Do not enter unnecessary personal data into prompts; anonymise where possible.
- Enable EU data residency where the provider offers it.
- Keep a professional in the loop: a security tool sees everything: log files, emails, usernames and network traffic.

Via pop-up windows in the HTML preview of code blocks, an attacker could bypass Lockdown Mode and siphon off your chat history, via a manipulated prompt, GPT or shared chat. OpenAI patched the flaw on 18 September 2026; Check Point published the details on 5 November. Users do not need to do anything. source
In the third quarter of 2026, OpenAI made more than 200 reports to law enforcement about threatened violence based on ChatGPT conversations. Conversations in which someone appears fixated on violence may be ended automatically by ChatGPT, and if it happens repeatedly, OpenAI can pause the account. So don't assume that what you type into ChatGPT stays confidential. source
ChatGPT can use plugins to search and summarise iCloud mail and change appointments, including on the free subscription. Signing in uses an app-specific password from Apple; it remains valid if you disconnect the integration in ChatGPT and you must revoke it yourself via account.apple.com. source
Questions
- How safe is ChatGPT for cybersecurity?
- ChatGPT has a strong published GDPR profile and, with the right business settings, is well usable in cybersecurity. EU options, no training on your data and/or self-hosting available.
- Does ChatGPT train on my data?
- EU data residency available for Enterprise, Edu and the API. Business and API data are not used for training by default; consumer tiers (Free/Plus/Pro) are, unless you turn this off.
- What should I watch out for with AI in cybersecurity?
- A security tool sees everything: log files, emails, usernames and network traffic. That is personal data, so you need a data processing agreement and must know where the data is stored. Also ask whether the AI assistant is trained on your data. WithSecure (Finland) says it processes data for Luminen in AWS in Europe and does not train foundation models on customer data. Sekoia stores data in Germany or elsewhere in the EU/EEA and is ISO 27001 certified. SoSafe (France) can run self-hosted. With Microsoft Security Copilot you choose the geo of your workspace, but sharing data with Microsoft is on by default. For Charlotte AI, ESET LiveAI and Mindgard the hosting location is not public. Never let an agent act on production systems without analyst approval, and record who makes the 24-hour report under the Cybersecurity Act when an incident occurs.
